The first part of this report describes a systems methodology which enables quantification of the trade-offs between various cost componnets of a pavement and selection of an optimum investment policy for any given situation. Through analyses of alternative pavement strategies, the methodology makes available to the decision maker the individual cost components and the total cost of each alternative. The second section of the report deals with pavement performance models that indicate distress caused by traffic loads and environmental conditions. Distress due to traffic was modelled using AASHTO Road Test performance data, and distress due to environment was modelled using the Brampton Road Test data. A final model was derived which has successfully predicted pavement lives in agreement with experience in actual situations.
